Abstract

A blockchain-based data processing method and apparatus, an electronic device, and a storage medium are provided, which are related to a field of blockchain technology and may be applied to cloud computations and cloud services. The specific implementation includes: acquiring a target chaining transaction request initiated by a target oracle based on a target oracle smart contract; acquiring other chaining transaction requests initiated by at least one other oracle based on the target oracle smart contract; and processing target off-chain data in the target chaining transaction request and other off-chain data in the other chaining transaction requests to obtain to-be-chained data based on the target oracle smart contract, and chaining and storing the to-be-chained data. A decentralized oracle is realized, and an authenticity of the off-chain data stored in the blockchain is ensured, thereby ensuring a reliability of an execution result of the business smart contract in the blockchain.
